11 Claims.

My invention relates generally to reels for lengths of material.

In the copending application of A. F. Kenyon and W. G. Cook, Serial No. 161,442,,filed'August 2B, 1937, there is described a systemfor providing a continuous feed for a strip rolling mill I which comprises welding the trailing end of the strip as it is moving toward the rolls to the leading end of the next succeeding reel of strip, continuing this process to provide continuous feed for the mill. Such a process has the advantage that the strip may be marketed in rolls of greater and more desirable lengths instead of in short' ally stated, isto provide strip reels that will iacilitate the operation of such a continuous mill.

A more specific object of my invention is to provide a reel which shall wind strip material in such a manner as to leave both ends of the strip accessible. 1

Another object of my invention is to provide a reel which shall function as an accumulating device so that strip material may be wound on the reel while the end of the strip remains substantially stationary.

A further object of my invention is to provide a reel which shall function as an accumulating device both in providing a continuous feed for a strip mill and in manipulating the reeling of strip material asit is continuously delivered 'from a stripmill.

These and other objects and advantages cf'the invention will be apparent from the following detailed description taken in connection with the accompanying drawing in which like reference characters designate like parts and in which winding reel of my invention,

Fig. 2 is a diagrammatic illustration of the use of the reel device of Fig. 1 as. a feed reel for a continuous feed rolling mill; and,

Fig. 3 is a'diagrammatic illustration of the "use of the reel device of Fig. 1 as an accumulating device for strip material as it is delivered from the reducing rolls and is being wound on reels.

.In carrying out my invention, I provide a reel 50 device which comprises clamping jaws or detents which .engage the strip of material to be wound approximately midway between its ends and then the strip on this reel so that the strip is wound thereon from two directions leaving both 55 ends of the material available.

or minimized, and that increased production re- Figure 1 is an illustration in perspective of the When used as a ieedreel for a strip rolling mill, the strip being rolled may be unwinding from the reel and passing through the mill while the other end of the strip is held substantially stationary so that one end of the next succeeding strip may be welded to it to provide a continuous feed for the mill. The reel may be used as an accumulating device between the delivery side of the :mill and the winding reel for the strip after. it has passed through the mill. When so used, 10 the end of the strip may be practically stopped to facilitate starting the strip on the winding reel while the stripes it is delivered from the mill is being accumulated on the accumulating reel. When'the winding reel has been threaded, 15 it winds the strip from the accumulating reel.

Referring now to Fig. 1 of the drawing, a base member ll mounted upon swivel rollers I! has mounted upon it a rotatable member or disc l3. Cam-like members H and I5 are mounted upon an the rotatable member I3 by means of pivots l6 and 17 which extend from the rotatable member l3 substantially parallel to, spaced from, and dis posed on opposite sides of the axis of rotation of the rotatable member 13.

The members 14 and I5 are so shaped as to nest together, as shown in Figs. 2 and 3, to form a substantially cylindrical surface to act as a reel core. The pivots l8 and I! are so offset with respect to the semi-circular ends l8 and IQ of members it and 55 as to provide a cam action between the members it and I5 so that they will grip the strip ofmaterial il when they are moved to nesting position. I

The rotatable member it may be driven in any suitable manner, such as by means of a motor, not shown, mounted in the base I i and connected in driving relation therewith by the belt and pulley arrangement 22.

In the operation of the winding reel, approxi- 4o mately one-half of the strip 2! is unwound from the reel 28 and the winding reel is moved into a position, with respect to the strip 2|, as shown in Fig. 1. When the rotatable member I3 is rotated in the clockwise direction, as viewed in Fig. 5 1, the cam members I t and i5 will move to nesting position, gripping the strip 2| and winding it from both directions from the point of con-' tact of the members It and IS with the'strip fl. Thus, it will be seen that when the strip 2| is wound upon the winding reel, both of its ends willbe on the outside of the reel and readily accessible, as shown in the reel 24 of Fig. 2.

In Fig. 2, there is shown a system for utilizing the reel of my invention as a supply reel for g5 providing a continuous strip of material for a continuously operating rolling mill. The strip 2i is being passed through the reducing roll stand 21 inthe direction of the arrow while back tension is applied to it by tension rolls 28. Pinch rolls 29 are provided for stopping one end of the strip as it unwinds from the reel 25. While the end of the strip is held substantially stationary by the pinch rolls 29, the strip 2| is being continuously passed through the reducing rolls and unwound from the reel which is moving wi h the strip toward the reducing rolls.

The joining machine 3| comprises a stand 32 which is mounted on rollers to facilitate movement and upon which are mounted a shearing device 33, a welding device 34 and a grinding device 35. These devices are provided for trimming the trailing end of the strip unwinding from reel 25 and the leading end of the strip to be unwound from reel 24 so that they may be matched for welding, welding these two ends together and grinding or otherwise finishing the welded joint so as to provide a continuous smooth strip. In this instance, the pinch rolls 29 are mounted on this stand 32 so that they may be moved therewith or they may be mounted separately if desired. After the welded joint has been finished the joining machine 3! is moved out of the path of the succeeding reel 24 which is moved toward the reducing rolls after reel 25 is unwound. The stop member 44 is provided to prevent the joining machine 3i from moving wit the strip as reel 25 is being unwound.

The pinch rolls 29 and the tensioning rolls 23 must be spaced a suificient distance apart to provide room for the travel of the reel 25 during the time necessary for performing the trimming, welding and grinding operations on the ends of the two lengths of strip that are being joined.

When the reel 25 is completely unwound, it may be removed from the strip and the reel 24 will then automatically move forward to take its place and successive reels of strip will be welded together in this manner while the mill 29 is continuously operating upon the strip.

In Fig. 3 of the drawing, there is shown the use of the reeling device described in connection with Fig. 1 as an accumulating reel for accumulating strip material as it is continuously delivered from a mill stand, while a portion of the material is stopped or slowed down when the winding reel becomes filled to permit cutting the material and starting it on an empty reel. The strip 2| is delivered from the mill rolls 21 in the direction of the arrow and is tensioned by the straightening device 36. When the reel 31 has wound a desired length of strip or become filled, and it is desired to start the strip on a new or empty reel, such as 38, the pinch rolls 39 are operated to stop the material so that shear I may cut the material to form a new end that may be started on to the new reel 33.

While the strip is stopped by the pinch rolls 39, the accumulating reel 23 is applied to the strip and when rotated in a clockwise direction, will wind strip as it isdelivered from the mill and will also wind the strip extending between it and the pinch rolls 39 by moving on its rollers i2 toward the pinch rolls 39.

The distance between the straightening rolls 36 and the pinch rolls 39 must be sufllcient to permit the movement of the accumulating reel 26 toward pinch rolls 39 which is necessary in winding the strip as it is continuously delivered from the mill during the time that the end oi. the strip has been unwound, it is moved back to a position near the straightening rolls 36 where it is ready to again act as an accumulating device for the strip when'it is again necessary to stop and cut the strip to start it on a new reel.

The controls for operating the several pieces of apparatus shown diagrammatically, such as the pinch rolls 29 and 39, tensioning rolls 28, straightening device 36, reducing rolls 21, shears 4i and 33, welding device 34 and grinding device 35 and reels 3! and 36, may be any control common in the art 'for manipulating such apparatus and these controls are, therefore, not shown or described in detail.

It will be seen that I have provided a winding 7 reel which may operate to wind 8. length of material so as to leave the two ends of the material readily accessible which may be used either as a supply reel for a system for providing a continudelivered from the mill, while parts of the material are being stopped, cut and started on succeeding receiving reels.
